which is operated by an eccentric d on the counter-shaft d through theadjustable connecting link or pitman CZ. Each of the punches oreye-forming dies F is operated as required by a cam f on thecounter-shaft (1 through the connecting-lever f link f and lever f. Aspring f retracts the punch F.

H represents extractor-pins to discharge or deliver the ring or Work Xfrom the holder after the ears 0: have been formed therein and the diesD D withdrawn and the workholder B brought back to its normal positionby the springs 13, so as to withdraw the ring X from the male dies C O,and thus permit the removal or discharge of the ring X from the holderB. The extractor-pins H fit in slots 17 in the work-holder B to permitthe necessary reciprocating movement of the work-holder. These.extractor-pins H are given the required reciprocating movements up anddown by means of a cam h on the driving-shaft G, which operates throughthe connecting-lever h, the inner arm of which is attached to aconnecting-bar 71, to which the extractor-pins are attached.

K is the clutch treadle or lever, by which the driving-shaft G isclutched to the loose power-pulley G. This clutch mechanism may be ofany suitable construction known to those skilled in the art. Theconnection, however, between the clutch lever or treadle and thecam-segment or block'K by which the clutch-pin is withdrawn ispreferably furnished with a safety-trip K operated by a cam K throughthe lever K to retract or disconnect the safety-trip,- and thus preventthe clutch-head from operating the clutch except at the proper time-that is to say, at the completion of each revolution,

In operation after the ring X is placed on the holder B, as illustratedin Fig. 5, the righthand exterior female die D advances against thecorresponding male die 0 and pushes the work-holder B with it,- thusforming one of the bail-ears at, and as this operation nears completionthe eye-forming punch F moves forward likewise and forms the eye or hole00 in the ear 0:. This die D then recedes and the opposite die D movesforward in like manner and forms the opposite car 00 on the other sideof the ring X. After this is done and the dies D D have both beenretracted the to, and a pair of reciprocating exterior earforming femaledies operating to form alternately first one bail-ear and then theother, substantially as specified.
